Lab: User role controlled by request parameter


This lab has an admin panel at /admin, which identifies administrators using a forgeable cookie.

Solve the lab by accessing the admin panel and using it to delete the user carlos.

You can log in to your own account using the following credentials: wiener:peter


  1. Browse to /admin and observe that you can't access the admin panel.
  2. Browse to the login page.
  3. In Burp Proxy, turn interception on and enable response interception.
  4. Complete and submit the login page, and forward the resulting request in Burp.
  5. Observe that the response sets the cookie Admin=false. Change it to Admin=true.
  6. Load the admin panel and delete carlos.
